Capt. Sara M. Knutson, 27, died Monday in Kandahar, the Pentagon said in a release. Knutson was assigned to Headquarters and Headquarters Company, 3rd Combat Aviation Brigade, 3rd Infantry Division, Hunter Army Airfield, Ga.
NATO reported the crash of the UH-60 Black Hawk helicopter in Southern Afghanistan earlier this week. Initial reports indicated there was no enemy activity in the area at the time, the coalition said.
The incident remains under investigation, the Pentagon said Saturday.
Also killed were Staff Sgt. Steven P. Blass, 27, of Estherville, Iowa; Chief Warrant Officer Bryan J. Henderson, 27, of Franklin, La.; Staff Sgt. Marc A. Scialdo, 31, of Naples, Fla.; and Spec. Zachary L. Shannon, 21, of Dunedin, Fla.
All, like Knutson, were assigned to elements of the 3rd Combat Aviation Brigade at Hunter Army Airfield.
According to the U.S. Military Academy alumni website west-point.org, Knutson married a former Black Hawk pilot in November and deployed to Afghanistan in January. She had served previously at Fort Wainwright in Alaska and deployed on a humanitarian mission to Pakistan.
The website, which identifies her as Sara Marie (Knutson) Cullen, said the helicopter crash Monday occurred during a training mission in heavy rain.
The crash and the deaths of two special operations forces shot by an Afghan policeman made Monday the deadliest day for U.S. troops in Afghanistan this year, accounting for half the 14 troops killed in 2013 so far.
Knutson was one of two service academy graduates from Maryland killed in air crashes on Monday.
